Hey, chas ... is this for all TY MID's you use? Or, just for TYG02? Sorry I don't have an explanation for you. If something concrete comes out of this, it may very well spoil the landslide of TYG02 scans posted in the Benq threads daily (possibly hourly). I hope it doesn't indicate that TYG02 turns out to be 'bad' media for Benq 1620's. I wonder if the LiteOn can't read the Benq 1620 burns as well (doubtful) or some other interpretation. I just loaded up on this stuff to use on my 1620.
Btw ... you mentioned the difference in the PIE max, but what about PIF max/ttls? Any difference there?
Does this mean you're comparing scans from TYG02 burned on Benq 1620 and LiteOn .. yet both scanned in the LiteOn? kProbe scans? Or, is it comparing the Benq 1620 burned TYG02 scanned in Benq 1620 CD-DVD Speed vs LiteOn kProbe?
